Mastic sealing in Priestwood, done properly

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. Most enquiries involve damaged joints in communal entrances and corridors and old repairs sealed over failed mastic, across shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Priestwood it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Priestwood, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Why act early in Priestwood

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Older rural buildings around Priestwood move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Why us?

  • Colour agreed before work starts
  • Standard and matched colours in many product ranges
  • Constructionline member for supplier checks
  • Joints cleaned back to sound surfaces

Questions about Priestwood

Is a smaller place like Priestwood outside your area?

Not at all. Priestwood is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on a block within reach of Sole Street station?

Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Substrate edges that need repairing first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

What we seal

  • Window and door perimeters on blocks
  • Communal kitchens and washrooms
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Balcony and threshold joints

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Block-wide mastic in Priestwood

At about 22 miles from central London, Priestwood is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Priestwood included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Blocks of flats and mixed-use buildings often cluster around stations such as Sole Street station, 1.9 miles to the north of Priestwood, and their window and balcony mastic tends to age at the same rate across a building. Churches, halls and community buildings such as Church of Our Lady of the Meadow are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like Meopham School can fit frame mastic into the summer works.

Surface by surface

External movement joints

The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. Jobs in and around smaller places like Priestwood are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

What we need from you

  • For older buildings, check the asbestos register before work
